Mama L [17]

Answer:

The density of the liquid in beaker B is less than the that of ice.

Explanation:

Ice will float if its mass is less than the mass of the liquid it displaces.

For example, the density of ice is less than that of water.

A 10 cm³ cube of ice has a mass of about 9 g, while the mass of 10 cm³ of water is 10 g. Thus, 9 g of ice displaces 10 g of water.

The denser water displaces the lighter ice and the ice floats to the top.

If the density of the liquid is <em>less than</em> that of water, say, 8 g/cm³, the ice will displace only 8 g of the liquid. The ice will sink.

Theobromine (greek theobroma, meaning "food of the gods") is a common constituent in coca. fill in all the lone pairs on each he
Ganezh [65]

The lone pair of electrons in Theobromine are shown in RED color in attached figure.

Details:

           In chemistry there are two types of electrons.

i) Bonding Pair Electrons:

                                        These are those electrons which are being shared and are involved in making bonds. They are also called as sharing electrons. In given structure all the solid bonds either single or double are made up of bonding pair electrons.

ii) Lone Pair / Non-Bonding Pair Electrons:

                                                                     Those electrons which doesn't take part in bonding and are not shared between atoms. In given structure the lone pair of electrons are found only on nitrogen atoms (single lone pair) and oxygen atoms (two lone pair of electrons) respectively.

Hybridization of Nitrogen Atoms;

                                                      N₁  =  Sp²

                                                      N₂  =  Sp³

                                                      N₃  =  Sp³

                                                      N₄  =  Sp³

Hybridization of Oxygen Atoms;

                                                      O₁  =  Sp²

                                                      O₂  =  Sp²
